Start by mixing together the flour, cheddar cheese, baking powder, dried basil, salt together.
Mix in the olive oil, egg, and milk
Spray your muffin tins with non-stick cooking spray (see blog post for the one I recommend)
Fill your muffin tins, about 2/3's full.
Set your air fryer to a temperature of 350 degrees F, and the time for 15 minutes.
After 15 minutes, check to see if the muffins are cooked all the way through, using a toothpick. If not cooked, add an additional 5 minutes. Check again.
Be careful removing the muffin tin, as it will be hot. Let slightly cool. Repeat with the batter, until you use all of the batter up.
Plate, serve and enjoy!
